E-A MODULATION SYSTEM DA CONVERTER WITH A BUILT-IN 8-
TIMES OVER SAMPLING DIGITAL FILTER/DIGITAL ATTENUATOR
The TC94OOF and TC9400N are a 2'nd order E-n modulation
system 1-bit DA converter incorporating an 8-times
oversampling FIR type digital filter and digital attenuator
developed for digital audio equipment.
Because the IC is small package (SSOP24, SDIP24) and the
de-emphasis filter has been incorporation, it is possible to
constitute reducing the size and cost of the DA converter.
TC9400F
